JOHN BERGESEN, OF NEW YORK, N. Y.

PROTECTIVE TUMBLING-HDOD FOR SHIPS HATCHES.

SPECIFICATION forming part of Letters Patent No. 700,012, dated May 13, 1902,

' Application filed February 18, 1901. Serial No. 47,786. (No model.)

To all whom it ntay concern:

Be it known that 1, JOHN BERGESEN', a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Protective Tumbling-Hood for Ships Hatches, of which the following is a specification.

The object of the invention is to provide a new and improved protective tumbling=hood for ships hatches and'the like, the,hood being simple and durable in construction, very eifective in operation, and arranged to shield the article to be protected against the wind or other current and also to tightly close the same when desired.

The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings,

forming a part of this specification, in which" similar characters of reference indicate corresponding parts in both views. I Figure 1 is a sectional side elevation of the improvement as applied to a hatch, and Fig. 2 is a similar View of the same with the hatch closed by the hood.

The improvement consists,;essentially, of a conical hood A, mounted at its apex by a; ball-and-socket or other universal joint 13 on the upper end of a screw-threaded rod 0, screwing into a nut of a support D in the} form of an inwardly-projecting arm attached to the hatch E, on which the hood is applied. As shown in the drawings, the universal joint B is formed by a ball on the upper end of the screw-threaded rod 0 and a socket on the inner face of the hood at its apex. The hood A is so supported that the base is a short distance above the'upper end of the hatch to allow the hood A to tumble in any direction,

3 according to the direction of the pressure of the wind on the side of the hood, the downwardly-moving portion of the base of the hood abutting against the corresponding upper end of the hatch E to limit the tumbling motion. of the hood.

' Now it will be seen that by the arranger ment described the hood tumbles by the force of the wind and in the direction of the wind, so that that portion of the hatch in the direction of the wind is closed by the hood, while the rest of the hatch is open to permit ventilation. It is expressly understood that the hood is hinged on the'support in such a manner that it changes its position by a tumbling movement, according to the direction in which the winds exerts a pressure on the side of the hood. 1

By turning the screw-rod O in the nut of the support D the hood A can be lowered and made to rest upon the upper edge of the hatch E, so as to close the same, as shown in Fig. 2. To insure atight joint between the hood and hatch when the hood is resting upon the hatch,

I provide a packing F on the outer surface of the hatch for the inner surface of the hood A to rest against.

In the apex of the hood A is arranged an oiling-plug G for lubricating the universal joint whenever necessary and for opening the hood from above.

While I have shown and described my invention as applied to hatches, yet I Wish it understood that it is equally as applicable to chimneys and thelike.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination with an inwardly-projecting arm secured to the upper end of the article to be'protected and provided with a nut at its free inner end, of a screw-threaded rod screwing into the nut of the arm and pro vided with a ball at its upper end, and a conical hood having a socket on its inner face at the apex to receive the ball of the rod, said hood being of a diameter considerably greater than that of the article and adapted to be seated on the upper edge of same, as set forth.

2. The combination with a'hatch having a packing around the'upper edge of its outer surface, of an inwardly-projecting arm havin g one end secured to the hatch and provided with a nut at its free inner end, a screwthreaded rod screwing in the nut of the arm and provided with a ball at its upper end, and In testimony whereof I have signed my a conical hood having a socket on its inner name to this specification in the presence of face at the apex and in which the ball of the tWo subscribing witnesses. rod fits, said hood being of a diameter con- JOHN BERGESEN.

5 siderably greater than that of the hatch and Witnesses:

adapted to be seated on the packing-ring at THEo. G. HOSTER, the upper edge of the hatch, as set forth. EVERARD BOLTON MARSHALL.
